Suborder Myomorpha contains 1,137 species of mouse-like rodents, nearly a quarter of all mammal species. Included are mice, rats, gerbils, hamsters, lemmings and voles. They are grouped according to the structure of their jaws and molar teeth. Both their medial and lateral masseter muscles are displaced forward, making them adept at gnawing. The medial masseter muscle goes through the eye socket, a feature unique among mammals. Myomorphs are found worldwide (apart from Antarctica) in almost all land habitats. They are usually nocturnal seed-eaters. Most myomorph species belong to superfamily Muroidea: *Superfamily Muroidea * *Family Platacanthomyidae * *Family Spalacidae * *Family Calomyscidae * *Family Nesomyidae * *Family Cricetidae * *Family Muridae *Superfamily Dipodoidea * *Family Dipodidae Historically, the definition of the suborder Myomorpha has included one or both of: *Superfamily Geomyoidea * *Family Heteromyidae * *Family Geomyidae *Superfamily Gliroidea * *Family Gliridae ==References== *Carleton, M.
